One of the key stumbling blocks in the uptake of battery electric vehicles is charging times. After all, who wants to wait eight hours to "fill the tank" when a gasoline, hybrid or hydrogen powered vehicle can be replenished in a matter of minutes. One of the projects seeking to address the issue is a collaboration between electric vehicle manufacturer THINK and charging infrastructure developer AeroVironment (a company best known to Gizmag readers as a manufacturer of UAVs). The companies are collaborating on a fast charging project for the THINK City electric vehicle with the goal of taking the EV from zero charge to 80 percent full in just 15 minutes.
